Math Problem Statement

Change the logarithmic equation \( \ln x = 5 \) to an equivalent equation involving an exponent.

Solution

To convert the logarithmic equation lnx=5\ln x = 5 into an equivalent exponential equation, we use the property of natural logarithms. The equation lnx=5\ln x = 5 means that xx is the number such that the natural logarithm (base ee) of xx is 5.

The conversion rule is: lnx=yx=ey\ln x = y \Rightarrow x = e^y

So, applying this to lnx=5\ln x = 5: x=e5x = e^5

Answer:

The equivalent exponential equation is: x=e5x = e^5

Here are five related questions to expand your understanding:

  1. How do we convert a general logarithmic equation with different bases to an exponential form?
  2. What is the approximate value of e5e^5?
  3. How do we solve for xx in equations of the form ex=ke^{x} = k?
  4. What are some applications of natural logarithms in calculus?
  5. How can we use logarithmic properties to simplify expressions like ln(ab)\ln(a \cdot b)?

Tip: Remember that lnx=5\ln x = 5 can be rewritten in terms of exponentiation with base ee, the base of natural logarithms, making conversions straightforward.
